Jake Shields’ win over Ed Herman at UFC 150 has been changed to a no-contest, and the fighter has also been fined $5,675.

A disciplinary complaint from the Colorado Department of Regulatory Agencies’ Boxing Commission also confirms a six-month suspension for Shields, who announced this past Friday that he’d tested positive for a banned substance.

MMAjunkie.com (www.mmajunkie.com) obtained a copy of the complaint, which became effective today. It did not disclose the substance for which Shields tested positive.

Shields (27-6-1 MMA, 2-2 UFC) defeated Herman (20-7 MMA, 7-5 UFC) via unanimous decision at UFC 150, which took place Aug. 11 at Denver’s Pepsi Center. The pay-per-view bout marked the ex-Strikeforce champ’s first fight at middleweight in more than two years.

According to the complaint, Shields was fined $5,000 for violating Colorado statutes on prohibited substances and ordered to pay a surcharge of 10 percent of the fine ($500), as well as $175 for administrative fees incurred for testing. He is ordered to pay the fines within 14 days.

Shields’ suspension runs six months, retroactive to Aug. 11. The complaint notes that conditions will be placed on the fighter’s license until he fulfills the terms of his suspension.

“This was a mistake that I fully regret,” Shields said in a prepared statement this past week. “I have shared this issue with my family and the UFC, and I have apologized to them, and now I also apologize to you, the fans. I promise this will never occur again in my fighting career.

“I accept the boxing commission’s decision for a six-month suspension, which will expire in February. I ask that you accept my apology. I will be back fighting soon, and hope that the fans of MMA will support me until that time.”

Shields and his representatives declined additional comment following the announcement this past week.

The UFC today released a statement about the situation.

“We’ve been informed by the Colorado Department of Regulatory Agencies’ Boxing Commission that Mr. Shields tested positive for a banned substance following his bout at UFC 150,” it read. “UFC has a strict, consistent policy against the use of any performance-enhancing drugs, including the requirement that all incoming athletes be tested and cleared for PEDs. Therefore, we fully support the drug testing efforts of the Colorado Department of Regulatory Agencies’ Boxing Commission and will fully cooperate with the Commission regarding this matter.”

As the UFC 189 tour made its last stop in Dublin, featherweight champ Jose Aldo was met with a torrent of abuse from the Irish fans. It might have been unpleasant, but it might also have been just what he needed.
